(History is reinterpreted, and it is taken as axiomatic that fascism must have been Right-wing, the logic seemingly being that Left-wing means compassionate and Right-wing means nasty and fascists were nasty.)

(On 16 June 1941, as Hitler readied his forces for Operation Barbarossa, Josef Goebbels looked forward to the new order that the Nazis would impose on a conquered Russia. There would be no come-back, he wrote, for capitalists nor priests nor Tsars.)

(Goebbels never doubted that he was a socialist. He understood Nazism to be a better and more plausible form of socialism than that propagated by Lenin. Instead of spreading itself across different nations, it would operate within the unit of the Volk.)

(Subsequent generations of Leftists have tried to explain away the awkward nomenclature of the National Socialist German Workers' Party as either a cynical PR stunt or an embarrassing coincidence. In fact, the name meant what it said.)

(Eugenics, of course, topples easily into racism. Engels himself wrote of the "racial trash" - the groups who would necessarily be supplanted as scientific socialism came into its own. Season this outlook with a sprinkling of anti-capitalism and you often got Leftist anti-Semitism.)
